[Elecraft] Dynamic Mics on K3

[Don Wilhelm]

Giulio,

You did not say what microphones you were trying to use, only that they 
were 'dynamic'.  Are you attempting to use Pro-Audio microphones?  If 
so, check out the information provided by Jim Brown K9YC at 
http://haminterfacing.pdf/.  Do your microphones have adequate output?  
Do they need Phantom Power?  There can be many reasons you are not 
having success.

How does the audio sound from the K3 monitor.  You said you did the 
evaluation on 144 MHz, but what mode?  If it is FM, then many have 
reported issues with 'thin audio' on FM, and Elecraft is currently 
working on improvement for that condition.  How does the K3 sound with 
the microphones on SSB?

73,
Don W3FPR
